bnxt allocates tables of max size, and changes the used size
based on number of active rings. The unused entries get padded
out with zeros. bnxt_modify_rss() seems to always pad out
the table of the main / default RSS context, instead of
the table of the modified context.

I haven't observed any behavior change due to this patch,
so I don't think it's a fix. Not entirely sure what role
the padding plays, 0 is a valid queue ID.
